CarBole E8012S Universal Inline Micro Fuel Pump 12V, 5/16" Fittings, 30 GPH Low-Pressure (5–9 PSI)

The CarBole E8012S is a compact universal inline micro electric fuel pump that delivers steady low-pressure fuel flow (30 GPH) for gasoline and diesel engines at 12V and 5–9 PSI.

This inline pump is built for general automotive and light industrial use where a small, quiet, reliable fuel feed is required. Its low-pressure design suits carbureted engines, auxiliary fuel systems, and replacement applications that need a compact 5/16" inlet/outlet connection. The pump is designed to run quietly while providing continuous fuel delivery and is cross-referenced to common part numbers so installers can confirm compatibility quickly.

How does this pump perform in everyday vehicle use?

The E8012S maintains a consistent flow rate and gentle pressure appropriate for many gasoline and diesel setups. It’s engineered for sustained operation and reduced noise so it integrates neatly into tight engine bays or under-dash installations.

• Flow rate: 30 gallons per hour (GPH) for steady fuel supply.
• Output pressure: 5–9 PSI suitable for low-pressure fuel systems.
• Designed for continuous service with low audible noise.
• Compact inline format fits easily in existing fuel lines with 5/16" fittings.

Will it fit my car, truck, or boat?

CarBole designed this unit for universal fitment across many gasoline and diesel applications, but it requires a compatible 5/16" fuel line and a non-alcohol fuel system. Check cross-reference numbers and measure your connections before installing.

• Universal application for many automotive and marine systems.
• Cross-reference codes: E8012S, FD0002, P60430, EP12S, 6414671 for verification.
• Requires 5/16" inlet/outlet hoses and a 12V power source.
• Not suitable for fuels containing alcohol; use only gasoline or diesel (no alcohol blends).

What installation and maintenance should I know about?

Installation is straightforward for anyone comfortable with basic fuel-system work: mount the pump inline between tank and engine, secure electrical connections, and always use a fuel filter upstream. Regular filter changes and a clean fuel supply will extend service life.

• Mount inline with correct 5/16" hoses and clamps to avoid leaks.
• Use a fuel filter upstream to prevent debris damage and clogging.
• Connect to a stable 12V supply with proper polarity and fuse protection.
• Inspect hoses and fittings periodically; replace filter per service intervals.

How reliable is this pump and what should I watch for?

The CarBole E8012S is built to provide reliable low-pressure pumping over extended use, but life expectancy depends on fuel cleanliness and correct installation. Running without a filter or using alcohol-containing fuels can shorten service life.

• Rated for continuous use with quiet operation and consistent flow.
• Expected long-term performance when used with proper filtration — designed for up to about 24,000 miles under good conditions.
• Avoid alcohol-blended fuels and dirty tanks to prevent premature wear.
• Contact seller support via message for product questions; 24-hour response promised.

Who is this for: The CarBole E8012S suits DIY mechanics, small-fleet operators, boat owners, and hobbyists who need a compact, quiet inline fuel pump for low-pressure gasoline or diesel systems. Choose this unit if you require a straightforward replacement or auxiliary pump with common cross-reference numbers and a compact 5/16" connection. Ensure your application uses non-alcohol fuels and includes a proper fuel filter for best results.
